Land wheels; shock-absorbers, applications of; floats, arrangement of.-An aeroplane is provided with a detachable float and land wheels to enable it to be used on land or water, and when both the land n-he.els and floats are attached, the land wheels can be adjusted to enable the machine to be used as an amphibian. A central float 5 of the usual hydroplane form is secured beneath the fuselage at four points by lugs and detachable pins. Small detachable floats are provided also beneath the wings. A trausverse shaft 12 extends through the fuselage and arms 16, hinged to lugs 15 at its ends, carry land wheels 17. Shock-absorbing struts 37 connect the arms 16 to arms 26 extending out from the shaft 12 and hinged to the lugs 15, this shaft being braced to the fuselage by two struts 20, 27, Fig. 11. A detachable bolt 19 passing through the lugs 15 screws into a forwardly directed strut 46 braced to the lower end of the arm 16 by a strut 47 having an eye surrounding a pin 49 on the strut 46. By turning the shaft 12 by mechanism not shown, the wheels can be moved from their operative position to a position above the level of the bottom of the fuselage. The pin 49 on the arm 16 is engaged in its two extreme positions by hooks 55, Fig. 9, on the fuselage, which are automatically closed by spring catches 56. These catches can be relased from within the fuselage by cords 58. The wheels can be independently detached from each side of the fuselage by removing the bolts 19 and the pins securing the struts 20, 27. The float 5 is detachable when the wheels are still in position.

Title: Improvements in check valve systems for hydraulic apparatus, such as master cylinders
IPC: B60T13/565
Filed: 1958-05-20
Abstract: 830,881. Hydraulic brakes. BENDIX AVIATION CORPORATION. May 20, 1958 (June 5, 1957], No. 16193/58. Addition to 687,304. Class 103 (1). A check valve assembly for controlling the flow into the pressure chamber 12 from the reservoir 28 of a master-cylinder for hydraulic brakes, generally similar to that described in the parent Specification comprises a seriallymounted compensating and one-way valve B adapted to control a frusto-conical opening 36 in a wall between a first chamber 28, i.e. the reservoir, and a second chamber 42 having a valve stem which extends through the opening and carries a valve member adapted to close the narrow side of the opening, and to be tilted to one side, whereby free flow of fluid may take place through the opening. By providing back pressure means in the form of chamber " C," there is substantially no flow through valve port 56 to the reservoir 28 due to the initial displacement of member 14, and the pressure begins to build up in chamber 12 from substantially the very beginning of the actuating movement. Since substantially no, or very little flow, proceeds through valve port 56 during actuation of the brake, movement of poppet 52 into engagement with partition 50 does not produce a rapid build-up of pressure such as to produce a " bumping " or unpleasant sensation to the operator. Specification 764,800 is referred to.

Patent GB-802574-A (GB)
Title: Ornamentation of textiles
Inventor: FEARNLEY CHARLES
IPC: D06P5/12
Filed: 1954-06-02
Abstract: Differential dyeing effects on textiles and films are produced by applying a resist to the textile or film before or during the dyeing operation and also, before the dyeing operation, applying in selected regions, a swelling agent for the textile or film, thereby modifying the effect of the resist in those regions of the area or areas treated or to be treated with the resist.  The process is applicable to textiles of synthetic polymers such as polyamides, polymethanes, polyaminotriazoles, polyesteramides, polyacrylonitrile and copolymers thereof and of natural or regenerated protein materials, especially wool, in the form of woven, knitted and matted fabrics, stubbings, rovings, yarns and coated cloth and also to films.  Specified resists are sulphur-containing organic compounds such as sulphurized phenols and naphthols and their substitution products, sulphonated products, metal-containing products, and condensation products with aldehydes or amino-aldehydic condensation products and other sulphonated bodies described in Specifications 552,015, 640,421 and 681,618, synthetic tanning agents such as those described in Specifications 375,160, 416,191 and 493,997, mono- or poly-isocyanates or -isothiocyanates and gaseous or wet chlorinating agents.  Suitable swelling agents for synthetic polymer materials are phenol, cresols, resorcinol, zinc chloride, calcium chloride dissolved in methanol, monochloracetic acid and other swelling agents described in Specification 708,753, for proteinaceous materials are sodium bisulphite, urea, urea-chloracetic acid, phenol and lithium bromide solution and for polyacrylonitrile materials are zinc chloride and mixtures of chloracetic acid and nitromethane.  Anionic dyestuffs are preferred although in certain cases basic dyestuffs may be employed, specified dyestuffs being those of the level dyeing acid, acid milling, chrome, direct, premetallized and solubilized vat classes, including fluorescent dyestuffs.  Dyestuffs having different affinities for the material or for different areas of the treated material may be applied together or in succession. The materials may be predyed, preprinted or prebleached and may also be pretreated with fluorescent brightening agents.  In the case of polyacrylonitrile materials, a cuprous ion mordant for the resist or for the dyestuff may also be applied.  Mechanical effects may be applied as described in Specifications 759,595 and 759,625.  Since the local application of the swelling agent also produces local shrinkage, seersucker effects may be obtained simultaneously.  The materials may be after-treated with, for example, tannic acid, formaldehyde or a resin precondensate, preferably of the melamine-, urea- or cyclic ethylene ureaformaldehyde type.  Examples describe the treatment of nylon, polyacrylonitrile and woollen fabrics, cotton-regenerated protein unions and caprolactam polymer yarns.

Abstract: 926,846. Road vehicle undercarriages. PRIMROSE THIRD AXLE CO. Ltd. May 13, 1960 [May 13, 1959; Nov. 13, 1959], Nos. 16352/59 and 38495/59. Class 108(2). In a hydraulic suspension for a vehicle, each axle 1, 2 is mounted on a leaf spring 5, 6 at each side of the vehicle and one end of each spring is carried at a fixed point 7, 8 on the vehicle chassis while the other end is carried freely by the movable element 15 of a double-acting hydraulic suspension means 17, the latter being interconnected so that a downward (or upward) thrust on one axle results in a substantially equal but opposite thrust on the other. To prevent slight deviations of one axle causing a flow of liquid an expansion chamber 33 containing a spring-loaded piston 39 may be provided, the piston being fully depressed or engaging a stop 42 when the vehicle is fully laden so that it has no effect on the flow of liquid. The ports connected to the conduit 38 may be at a higher level on the means 17 so that the conduits may be connected to the chassis by common clips. The means 17 may consist of diaphragm chambers instead of rams.

Abstract: 809,785. Ornamenting. NEUGASS, E. A. June 8, 1955 [April 25, 1955], No. 16847/55. Drawings to Specification. Class 93 [Also in Group VIII] A rigid panel having indicia capable of being made visible by interal illumination as well as by ambient light is produced by superposing a translucent light-coloured plastic sheet material on at least one-surface of a transparent body placing the superposed members between platens one of which bears the desired indicia in intaglio and' confronts the translucent sheet, hot pressing said sheet to bond it to the transparent body and to form raised indicia on the translucent sheet, applying on opaque dark-colouredcoating over the translucent sheet as by spraying, and removing the dark coloured coating from the raised in- 'dicia. The thickness of the dark coloured coating may be either the same as the height of the raised indicia which when exposed lie flush with the surface of the dark coating, or less than the height of the raised indicia when the dark coatings on the sides of the indicia may be either allowed to remain or wholly ar partly removed, particularly when the raised indicia are of triangular vertical crosssection. The transparent body may be polymethylmethacrylate, the translucent sheet may be plasticized vinyl chlorideacetate copolymer, and the opaque coating may be vinyl-base'paint which is baked to harden it. If desired the translucent sheet and opaque coating may be elastomeric. To improve uniformity of illumination of the indicia by transmitted light, a white paint may be applied to the back surface of the transparent body adjacent indicia located some distance from a light source and/or black paint may be applied adjacent indicia dose to the light source, as by applying white paint over the whole of the back surface of the body, removing the paint adjacent indicia close to the light source, and applying a further uniform coat of black paint.

Title: Improvements in and relating to prepayment mechanism for meters and the like
IPC: G07F15/02
Filed: 1942-11-27
Abstract: 566,173. Coin-freed meters. CROMPTON PARKINSON, Ltd., and ANGOLD, A. W. Nov. 27, 1942, No. 16880. Addition to 515,223. [Class 27] The apparatus of the parent Specification is provided with means to prevent the insertion of another coin into the mechanism after the slot obstructing slide has returned until the previous coin has been cleared and credited. A fixed upper jaw 122 to the coin inlet is now fitted, between which and the lower jaw 123, on the sliding plate 14 the coin is inserted, both jaws being grooved to facilitate entry of the coin, rollers 125 on the plate 14 running on the edges of the plate 8 in which is the coin slot. A lug. 126 extending back from the plate is cranked at 127 and attached to a spring 45. The Figure shows a coin x in the gauging pocket being gauged by a feeler 33, which is lowered by spring action against the coin standing on the platform 35 swung by its lugs 37 from a pivot 38 carried in the arms 39 of a bracket 41, as described in the parent Specification. Also as there described, the latch 68 pivoted at 70 is only lowered to free the crediting mechanism when a coin x is depressed by the spring- pressed caliper feeler 33 to rock the bracket 41. The latch 68 is now fitted with an arm 128, the rear edge of which is normally vertical so that the crank 127 passes behind it while the coin passes through the inlet slot. After this the spring 45 returns the slide 14 to close the slot and urge 'the coin into the gauge where the bracket 41 rocks down at 71 against the upturned end 130 of a blade spring 129 riveted to the latch lever 68, 69, 128 near its pivot. The blade spring is urged up by a spring 131. Thus, the gauging of the coin frees the crediting gear for manual setting, during which the arm 128 prevents entry of a coin ; when crediting is complete, the blade spring removes the lock 128 from the slide crank 127 and the latch 68 relocks the credit mechanism. The movement of the inlet slide 14 may urge the coin into the gauge by the means described in the parent Specification or by the mechanism described in Specification 562,979.
